Divided and this application tiled Inly 2a, 1919. serial No. 313,800.

Be it known that l, FERNANDO Osma JAQUES, Jr., a Citizen of the United States, residing at Providence. in the county of Providence andA State ot' Rhode island. have invented a new and useful improvement. in Means for Making Castellated Nuts, ot' which the following is a specification.

This application is a divisional applica; tion. divided from my application for a Patent No. 1,314,668 on means for making castellated nuts. filed February 28. 1919, Serial No. 279,742. division required June 21, 1918, and has for its object all ot' the objects given inv said application.

My invention eonsists in the peculiar and novel construction and operation of means for making castellated nuts. as will be more fully set forth hereinafter and claimed.

Figure 1 is 'an end vie-w of the plunger member. l

'Figure 2 is an end view ofthe and castellating member.

Figure B'is a side view of the plunger nut holding membel' and a sectional view of the'nut holdlng and castellatmg member, showing themembers separated and anni; blank in position to be castellated.

Figure is a sectional view Vsimilar to Figure 3 .showing the members closed and astellated. und

`Figures 5 and (l are top and side views respectively of the eastellatedl nut.

IIx-the drawings 7 indicates a plunger member, 8 a nut holding and rastellating member, 9 a nut blank and 10 a rastellated nut. l

The plunger member T form, it has a sliding tit in the member S. and a round central hole forming stud 1l which protrudes trom-tbe end of the plunger-.as shown in Figure il.

The nut holding and eastellating member 8 has a hexagonal shaped eavity 12 tht-size of the plunger Zand ot' the nut to be. vastellated. 2, 3 and l has a fiat nut bottom lil in which is: a round bore i4 whieh extends eentrally through the bottom` 13. v.kmovablel stud member l5 having the same size and shape as the stud ll, is'mo'vably supported in the bore 141*-- and extends into the Adistiatnee required, when the mit is being easeavity 12, the

tellated. Projecting eastel'lating members 16. 16 are formed on the bottom 13 and on the sides. and surround the bore 14. said projet-ting rastellatlng members being- When in use 'a nut blank 9 is plaeed in the cavity 12 with themovable stud member 15 protruding into the cavity. as shown in Fig- The members' 7 and 8 are -now brought together under the required pres sure. thereby forming the castellations 1T. l? on the-nut blank. as shown in Figures 5 and 6, and the studs 11 and 15 simultaneously' entering the blank. formsthe. greater portion ank, leaving a. thin transverse web 19,'i1s shown in Figure 4. The members-7 and-S are now separated and the movable' stud member 15 operated against the web 19 to push the casteliated nut out of the Cavity 12 Whereit is removed by an air blast or other means. In completing the nut the thm web 19 ispunched out and the hole thus` formed screw-threaded in the usual As the nut blank Anow has just the right amount of metal to form the rastellations and'thegreater portion of the hole inthe nut. all of the metal heretofore wasted'fin .forming the eastellations is saved and" the greater portion of the metal heretofore lost in drilling the hole is also saved and b v con'- densing the metal by pressure a more pert'ert 'and durable eastellated mit is produced.

prising a member having a eu'vity the shape Aand size of the. nut to be eastellated. proje -t' ing members in said cavity adapted to form oastellations on the nut. and a member havinga sliding tit in said eavity. whereby on foreing the last mentioned member into said eavity. enstellations are formed on the nat by eompressing the metalof the mit.
